GOATED STRIP AND METHOD OF MAKING THE SAME.

Specification of Letters Patent.

Patented. Feb. 27, 1906.

Application filed July 10, 1905. Serial No. 269,120

To all whom it may concern:

Be it known that we, HENRY S. CHAPMAN, residing in Glenridge, New Jersey, and WIL- BUR M. STONE, residing in New York, State of New York, citizens of the United States, have invented certain new and useful Improvements in Coated Stri s and Methods of Making the Same, of whicli the following is a s eclfication.

his invention relates to coated strips and to the method of coating the same, and has for its object to furnish a strip of material, articularly such material as is normally able to deterioration by oxidation or otherwise, with a coating of material impervious to moisture or with a material which will provide a protecting or ornamental cover to the.

strlp.

Ourimprovement isillustrated in the drawings accompanying this specification, and in which drawings 1 Figure 1 is a plan view of a strip embodying our improvements and made in accordance with our improved process. Fig. 2 is a section on line a a of Fig. 1. Fig. 3 is a section on line b b of 1. Fig. 4 is a plan view similar to 1, but showin the coht:

ed strip with reinforced edges. ig. 5 is a sectionon line 0 c of Fig. 4. Fig. 6 is a section on line d d of Fig. 4. Fig. 7 is a plan view of another form of our improvement. Fig. 8 is a section on line e e of Fig. 7. Fig. 9 is a section on line f f of Fig. 7. Fig. 10 1s a vertical section .on hne g of Fig. 11 of one form of a device by which tion of our im roved process. Fig. 11*is a plan view of t e same. Fig. 12 is a detail plan view of a pair of scraper-j aws for putting on the edge beads of Figs. 4, 5, and 6.

When made u with steel strips as a base and a coating 0 pyroxylin compound, our improved coated strips are es ecia ly applicable for use as corset-steels an stiffening stays for garments and the like, whereby a rustless stiffening-strip is provided and one in which the edges and ends are so rounded as to present no sharp edges or corners towear or out through the garments in which they are used. With these ends in view our improvement comprises in one of its forms a strip of suitable material-such as steel, whalebone,

' bamboo, or other rigid materialhaving we carry out a porthereon a seamless incasin coating of celluloid, pyroxylin, rubber, acquer, or other analogous material which is susceptible of being dissolved for use in carrying out our improved process. Fig. 2 illustrates a crosssection of such a strip in which a base of steel or other suitable material 2' is incased in a seamless coatin 3. This coating is applied in liquid form iy any suitable means, but preferablycontinuousl to a continuous strip, as hereinafter more ly set forth. In 10 and 11 we have illustrated one form of an apparatus for applying said coating. ThlS apparatus comprises a tank 20 for holdingsthe solution to be applied to the strip. aid tank is furnished with a hole 21 in the bottom thereof, through which the continuous strip 1 may be passed. Said hole 21 is provided with. a gate 22, of leather or some other suitable yielding material, the edges of which will engage the strip and prevent the solution from leaking from the tank. Also when the strip is removed said edges will engage each other to prevent leakage. Extending inwardly through opposite sides of the tank and near the bottom thereof are guides 23 24, and near the to thereof are guides 25 26. These guides ave vertical notches in their inner ends, respectively, and which notches enga e the strip to be coated and direct it verticaly in an unvaryin between the inner ends, respective? scraper-jaws 27 28. These jaws are adjustably secured to side walls 29 30 by means of screws 31 32, all respectively. By these means the thickness of the coatin pplied to the strip may be regulated at Guides 23 24.25 26 are adjustable in and out, and wider scraper-jaws may be used, whereby the apparatus may be operated to coat stripsof any desired width Within its capacity.

In the practice of our improved process we proceed as follows: The tank 20 is first filled with the desired coating solution, preferably to a level somewhat above guides 25 26, so that if the coating fluid is scra d ofithe edges of the strip by said guides t e strip will have opportunity to be recoated before passing between scraper-jaws 27 28. One'end of.

path

24 and 25 26, respectively, wardl between the noses of serap'er' jaws 27 28. aid jaws are then adjusted in such proximity to the respective sides of the strip as to scrape off the surplus coating liquid and allow the desired amount to remain thereon. If the coating fluid is sufficiently quick-d1 mg, the continuous coated strip may now e le upward a sufficient distance to give the coating time to dry and may then be coiled or spooled ready for the next step in our process, or if a heavier coatin is desired than can be conveniently ap lied the strip may be passe through the coatingbath one or more additional times. If the coatingliquidis slowin dryin ,the continuous strips may be cut into handleable lengths say six to twenty feetas it passes out from the coating-bath and these lengths hung up or otherwise dis osed for drying.

To produce the strip of Figs. 1, 2, and 3, the continuous strip is now out into suitable lengths, preferably with the ends of each length suitably rounded, as at 4, and then eac nish a protecting and finishing cap 8 thereon, F' 1 and 3.

ith some coating fluidssueh, for instance, as a solution of celluloidthe tendency thereof in drying is to so shrink on the flat surfaces of the strip as to ull away-more or less from the edgesthereof: whereby said edges are left insufficiently coated. To remedy this lack or to supply reinforcing edges and thence upto the coated strip, even though said strip.

be equally coated on ed es and faces, we proceed as follows: In tan 20 we substitute aws 37 38 for jaws 27 28. Said jaws 37 38 have their noses cut back on each side at 370 380, respectively. Said nosesare set in close proximity to the previously coated and dried aces of the stri allrespectively, and the strip fed upward y therebetween. The coat ing liquid is thereby scraped off from the middle portions of said coated faces and allowed to remain on the edges of the stri and inreaehing a short distance therefrom. pon drying, a reinforcingbead 5 .5 is thereby formed on each edge, Figs. 4, 5, and 6. The continuous strip may then be cut into suitable lengths and their ends coated, as already desc 'bed.

Another feature of our invention comprises the a l of an incasing coating to strips revi iislfi overed with cloth, paper, or simiar materials. By this rocess we are able to produce a coated strip, igs. 7, 8, and 9, havmg a wear-resisting cover of fabric or similar material 6, impregnated and coated with a finishin material 7, waterproof or otherwise, as desired, thereby affording additional strength and beauty to the product. The cloth or paper may be applied by any suitable means to the continuous strip and the in-one operation end is dipped in the coating fluid to furthen covered strip be fed through the coatingbath one or more times and with or without a reinforcing-bead formed on the edges thereof, as desired. The strip is then cut up into suitable lengths and the ends capped, as already described in connection with Figs. 1 to 6, inelusive.

Byscraping as herein used is meant a removal by a blade, brush, roller, or any similar means.

Having thus described our invention, we claiml. A ri 'd stri having a seamless incasin coating 0 semip astic material and a secon coating of similarmaterial on a portion thereof, sai second portion forming a reinforcingbead thereon.

2. Ari 'd stri having a seamless incasin coating 0 semip astic material and a secon coatin of similar material on portions thereof, said second portions forming reinforcingbeads lengthwise thereon.

3. A strip having a seamless incasing coating of semiplastic material, a reinforcingbead on each edge thereof and a reinforcin cap on each end thereof, said beads and caps being of the same material as the coating.

4. A strip having a seamless incasing coating of semiplastic material, a reinforcingbeadon each edge thereof and a reinforcingca on each end thereof, said beads and caps being of the same material as the coating and integral therewith.

5. A strip having a covering of fabric, paper or other material and a seamless incasing coating of semiplastic material thereover and a reinforcing-cap on each end thereof of the same materlal as the coatin 6. A strip having a covering of fabric, pa per or other material and a seamless im re nating and incasing coating of semip astlc material thereover and a reinforcing-cap on each end thereof of the same material and integral with the coating.

7.
